Victims of Racket: Entrepreneurs and Traders Dealing with Cosa Nostra, Ndrangheta, and Camorra

2015

This work proposes research on a still unexplored psychical world: thoughts, emotions, and real events experienced by racket victims of the three largest criminal organizations of the South of Italy: Mafia, Camorra, and Ndrangheta. The purpose is to understand the multifaceted psycho-anthropological and social issues criminal organizations have settled on, and particularly which psycho-relational dynamics and sociocultural codes come into play in the complex and controversial relationship between victim and criminal system, between victim and support systems. With entrepreneurs and tradesmen victims of organized crime, we have analyzed lived experiences - in particular fear - and psychologi…

Match analysis of wheelchair padel players of different functional level

2018

The aim of this study was to quantify the kinematic demands of wheelchair padel and to examine the activity profiles in professional players according to their functional level. Twenty-two elite players classified in functional level groups (from 1 to 4) were video-analysed with a two-dimensional DLT corrected video system across seven matches of a professional tournament. The results showed players covered 729.6 ± 369.9 meters and 238.45 ± 129.45 turns per match during 1128.9 ± 583.04 second of effective playing time at a mean speed of 0.53 ± 0.49 m/s per rally. The WCP players’ functional classification had heavy influence on their activity profiles during matches, with a large associatio…

Orthodontic Treatment and Healthcare Goals: Evaluation of Multibrackets Treatment Results Using PAR Index (Peer Assessment Rating)

2020

Background: The evaluation of orthodontic treatment outcomes using an objective method is important in order to maintain high treatment quality and final healthcare of patients. It allows professionals and university students to raise the level of the therapy. The aim of this study was to assess the orthodontic treatment outcomes in an Italian postgraduate School of Orthodontics using Peer Assessment Rating (PAR) Index. Methods: A sample of 50 patients treated in a postgraduate program was randomly selected. PAR index was used to assess pre-treatment and post-treatment study casts by two different examiners. The influence of different variables such as gender, treatment method, and need for…

Estudio presurométrico y biomecánico del pie en el pádel

2014

[EN] Padel is a very popular sport in countries like Spain, Argentina and Brazil, but there is a lack of scientific papers analyzing the harmfulness of their practice. Padel movements could potentially damage the foot and ankle joint. Therefore, the objective of this study was the characterization of the foot role during the execution of the most representative padel movements by techniques of pressurometry and video. The study was divided in two parts: pressurometric analysis of two movements (head-on displacement and split-step), and video recording of the foot during two games. The main conclusions of the study are the importance of forefoot zone in the padel movements, the importance of…

Comparison of frictional resistance between passive self-ligating brackets and slide-type low-friction ligature brackets during the alignment and lev…

2019

Background To compare the frictional resistance between passive self-ligating brackets and conventional brackets with low-friction ligature under bracket/archwire and root/bone interface during dental alignment and leveling. Material and methods A tridimensional model of the maxilla and teeth of a patient treated with conventional brackets, and slide ligatures was generated employing the SolidWorks modeling software. SmartClip self-ligating brackets and Logic Line conventional brackets were assembled with slide low-friction ligatures, utilizing archwires with different diameters and alloys used for the alignment and leveling stage. Friction caused during the bracket/archwire interface and s…

In vitro comparative study on the friction of stainless steel wires with and without Orthospeed (JAL 90458) on an inclined plane

2016

Background: During the treatment of orthodontics, in the mechanics of slide, there takes place friction, which they reduce the slide of the arch across bracket. Therefore, clinical there takes place an increase of the time of treatment. There are different the technologies that try to reduce this friction, as the self-ligating braces. The purpose of this study was to research the in vitro behavior of JAL 90458 as a buffering agent which reduces friction between brackets and stainless steel arch wires of different cross sections and sizes. Material and Methods: Three types of stainless steel wires with different cross sections and three types of ligatures were used with and without JAL 90458…

Novel Digital Technique to Quantify the Area and Volume of Cement Remaining and Enamel Removed after Fixed Multibracket Appliance Therapy Debonding: …

2020

The aim of this study was to construct a novel, repeatable, reproducible, and accurate measurement protocol for the area and volume of the remaining cement after removal of fixed multibracket appliances, the area and volume of remaining cement after cement removal, the area and volume of enamel removed after cement removal, and the volume of cement used to adhere fixed multibracket appliances. A total of 30 brackets were cemented and removed with over 30 extracted teeth embedded into three experimental models of epoxy resin. The models were scanned before and after bracket placement, bracket debonding, and polishing the remaining cement. The brackets were submitted to micro-computed tomogra…

Recent Anti-Mafia Strategies: The Italian Experience

2008

We often tend to think of criminal policies as essentially repressive. At first sight this assumption seems to apply straightforwardly in the case of policies against organized crime, especially those targeted at mafia type organizations. However, experience shows that these criminal organizations can be fought successfully also by means of measures which are not in themselves repressive, albeit they aim to favour repression in the last resort. Together with direct repressive measures, in the Italian case we indeed register a wide variety of other policies addressing civil society and public administrations, and only indirectly the mafia. Indirect strategies, therefore, are aimed at the rei…

Estudio de la fuerza de adhesión de brackets metálicos y cerámicos sobre superficies de zircona tratadas con láser de femtosegundos

2017

Objetivos: 1) Analizar los estudios publicados sobre los efectos de diferentes láseres en la adhesión a superficies de cerámica; 2) determinar los parámetros ideales del láser de femtosegundos para conseguir una adhesión óptima bracket-zircona; 3) analizar los efectos del láser de femtosegundos en la fuerza de adhesión de brackets metálicos y cerámicos sobre zircona; comparar la fuerza de adhesión entre brackets cerámicos y metálicos a zircona. Material y métodos: El trabajo se dividió en tres partes. 1.Revisión sistemática de la literatura y meta-análisis para determinar qué tipo de láser es el más efectivo para adherir cementos y composites sobre superficies de cerámica. 2.Estudio in-vitr…
